+### Changed
+
+- `query_platform/4` now handles all 2xx status codes as success, returning `{:ok, body}` with the raw response body. Previously only `200` responses with a `%{data: data}` GraphQL structure were treated as success, causing non-GraphQL platform APIs (e.g. ACME) to incorrectly fall through to the error path.
